Degradation of transformer oil on the basis of polychlorinated bifenyls without degrading the existing quality of the environment / Degradacija transformatorskog ulja na bazi polihlorovanih bifenila bez narušavanja postojećeg kvaliteta životne sredine
(Elektroprivreda, 2003)
This paper deals with results of laboratory experiments referring to transformer oil chemical degradation on the basis of polychlorinated bifenyls, results referring to rinsing of transformer insulation material, as well ...
The roughness analysis of metal coatings by STM technique part III: Analysis of copper coatings electrodeposited with thiourea as brightening additive / Analiza hrapavosti galvanskih prevlaka tehnikom skenirajuće tunelske mikroskopije III deo - analiza prevlaka bakra istaloženih sa tioureom kao aditivom za sjaj
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work is given the analysis of roughness of copper coatings electrodeposited from a sulfate bath in the presence of thiourea, by methodology which is described in part I of this work. It was shown that the ...
Hydrogen Evolution on Zeolite Supported Platinum Clusters
(Wiley-VCH, 2003)
NaX type zeolite was loaded with platinum, by the thermal decomposition of Pt(II) acetylacetonate, up to the Pt/NaX mass ratio 0.174. The sample, dispersed on a glassy carbon rotating disc, was used in slightly acidic ...
Chemical modification of β-lactoglobulin by quinines / Hemijske modifikacije β-laktoglobulina hinonima
(Serbian Chemical Society, 2003)
The avarone/avarol quinone/hydroquinone couple, as well as their derivatives show considerable antitumor activity. In this work, covalent modifications of β-lactoglobulin, isolated from cow milk, by avarone, its model ...
Comparisons of formic acid oxidation at supported Pt catalyst and at low-index Pt single crystal electrodes in sulfuric acid solution / Poređenje oksidacije mravlje kiseline na PT katalizatoru na nosaču i na niskoindeksnim PT monokristalima u sumpornoj kiselini
(Serbian Chemical Society, 2003)
The oxidation of formic acid was studied at supported Pt catalyst (47.5 wt%. Pt) and a low-index single crystal electrodes in sulfuric acid. The supported Pt catalyst was characterized by the TEM and HRTEM techniques. The ...
Sesquiterpene lactones from the aerial parts of Inula oculus-christi
(Elsevier, 2003)
Pulchellin E (1) and gaillardin (2) were isolated from the aerial parts of Inula oculus-christi, along with the flavone hispidulin. The C-13-NMR chemical shifts of 1 and 2 are reported.
Electrical Conductivity of Fullerene Derivatives
(Trans Tech Publications, Switzerland, 2003)
In this paper electrical conductivity of fullerene derivatives was investigated. Compared with pure fullerene (molecule C60), which is an insulator (10-12 Sm-1), the measured C60(OH)24 shows several order of magnitude ...
Hyperatomarin, an antibacterial prenylated phloroglucinol from Hypericum atomarium ssp degenii
(American Chemical Society (ACS), 2003)
As shown by quantitative 1H NMR measurements, a lipophilic extract of the aerial parts of Hypericum atomarium ssp. degenii contained a high percentage (3.1% per weight of dried plant material) of a prenylated phloroglucinol ...
Osmotic coefficient of the ZnCl2(aq) at T = 298.15 K
(Elsevier, 2003)
The osmotic coefficient of ZnCl2 (aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4)mol·kg -1 with KCl(aq) as the reference solution. The available literature data ...
Further degradation product of hyperforin from Hypericum perforatum (St. John's Wort)
(Elsevier, 2003)
Repeated examination of the aerial parts of Hypericum Perfomtum yielded a new degradation product of hyperforin (1) namely deoxyfurohyperforin A (2), together with the previously identified furohyperforin (3), furoadhyperforin ...
